Here, we adopted a hierarchical approach to test the contribution of region, landscape heterogeneity, local management (organic vs. conventional) and location within field (edge vs. centre) to the species richness and abundance of spiders in cereals.Location Three regions of western and central Germany: Leine Bergland, Soester Boerde, and Lahn-Dill Bergland.Methods Forty-two paired organic and conventional winter wheat fields were compared. Field pairs were located in areas ranging from structurally simple to structurally complex landscapes. In May and June 2003, spiders were sampled using pitfall traps. Linear mixed models were used to determine the relationship of spider diversity and abundance with regional spatial factors and landscape heterogeneity within a 500-m radius, as well as with local management and within-field location.Results Within-field location of the traps and landscape heterogeneity were the best predictors of species richness: more species were found in field edges and in heterogeneous landscapes. Region and local management had no effect on species richness. Activity density was higher in field edges and differed among regions.Main conclusions The diversity of farmland spiders was influenced by differences at two of the spatial scales (edge vs. centre, simple vs. complex landscapes), but not at the two others (field management, region), emphasizing the importance of analyses at a variety of spatial scales for an adequate explanation of patterns in biodiversity. Our study suggests that promoting heterogeneity in land use at landscape scales is one of the keys to promoting spider diversity in agroecosystems."],["dc.identifier.doi","10.1111/j.1365-2699.2005.01367.x"],["dc.identifier.gro","3149799"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/6497"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.relation.issn","0305-0270"],["dc.subject","Agroecosystem; Araneae; biodiversity; biological control; cereals; landscape composition; organic farming; regional variation; scale effects"],["dc.title","Spider diversity in cereal fields: comparing factors at local, landscape and regional scales"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]

Scheme design is partly based on non-ecological considerations and poses important restrictions on evaluation studies. We describe a robust approach to evaluate agri-environment schemes and use it to evaluate the biodiversity effects of agri-environment schemes in five European countries. We compared species density of vascular plants, birds, bees, grasshoppers and crickets, and spiders on 202 paired fields, one with an agri-environment scheme, the other conventionally managed. In all countries, agri-environment schemes had marginal to moderately positive effects on biodiversity. However, uncommon species benefited in only two of five countries and species listed in Red Data Books rarely benefited from agri-environment schemes. Scheme objectives may need to differentiate between biodiversity of common species that can be enhanced with relatively simple modifications in farming practices and diversity or abundance of endangered species which require more elaborate conservation measures."],["dc.identifier.doi","10.1111/j.1461-0248.2005.00869.x"],["dc.identifier.gro","3150073"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/6801"],["dc.language.iso","en"],["dc.notes.status","public"],["dc.relation.issn","1461-023X"],["dc.subject","Biodiversity conservation; European Union; farmland wildlife; land-use intensity; policy evaluation; Red Data Book species"],["dc.title","Mixed biodiversity benefits of agri-environment schemes in five European countries"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]
